Tech info
Resources

LTDM series are high power diffuse LED strobe dome illuminators designed to provide non-directional diffused light and to effectively eliminate glare and shadows. 

LTDM series provides ultra-high power light output and can be used to illuminate complex shapes with curved and shiny surfaces.
LTDM dome illuminators can be exclusively operated in strobe mode, making them the perfect choice to illuminate very fast moving objects while ensuring extended LED lifetime since no heat is generated.

LTDM series can be easily powered, controlled and synchronized by compatible LTDV strobe controllers and is available in:

  • three sizes: small, medium and large, respectively with illumination area of 40 mm, 60 mm and 100 mm in diameter;
  • two power intensities: medium power with driving current up to 7.5 A and high power with driving current up to 17 A;
  • three different colors: white, red and green.

LTDM series feature industry-standard connection (M8 or M12 four poles connector) and resizable aperture that can be drilled to increase the diameter and accommodate the optics field of view. Additionally they can be easily integrated into any machine vision system by means of M6 screws.

KEY ADVANTAGES

  • Ultra high-power light output and strobe mode only operation
    For the inspection of fast moving object and an extended LED lifetime.
  • Rugged industrial design with built-in industrial connector
    For easy integration into any machine vision system.
  • Wide selection
    Available in three sizes, three colors and two power intensities.
  • Compatible LTDV strobe controllers available
    For easy and appropriate power, control and synchronization of the illuminator.

DESIGNED FOR OEM APPLICATIONS

  • Compatible LTDV strobe controllers available to easily power, control and synchronise LED illuminators.

Application cases

Image with white dome light vs Image with red dome light
High speed OCR on food cans with LTDM strobe LED dome light and fixed focal lens. The red wavelength works well on orange/yellow cans and increases the contrast of the expiration date with respect to the can background so that the image can be easily processed by machine vision algorithms.

  2. At 25°C. At max pulse width (1 ms), max pulse frequency = 15 Hz.
  3. At 25°C.

Ordering information

Our part numbers are coded as LTDMxy-z, where x defines the illuminator size (A = small, B = medium, C = large), y refers to the power intensity (1 = medium, 2 = high) and z refers to color (W = white, R = red, G = green).

For instance LTDMB2-R is a diffusive strobed dome illuminator - medium size high power red.
